Synopsis
int bindrv_getdata(s_bindrvctx bctx,void **val, size_t *size);
Arguments
bctx 
A BinDrv reader context
val 
Pointer to return a reference to the data buffer

Return value
0 if successful, a negative value in case of error or the type code of the token (positive value) if it is not of the expected type.
Further information
1. The returned buffer is allocated using the C function malloc. To replace this default memory allocator, ( e.g. by some application specific memory management routine), use bindrv_setalloc.
2. The buffer reference will be NULL and the size will be 0 when an empty block is encountered.
